I've always had a pretty big problem with clenching my jaw when I was angry. I still do that if I'm mad or stressed, to me it's better than yelling or makinga seen (kind of an intense person ). I also noticed that when I was falling asleep I would begin clenching my teeth together. I've since tried to make a concious effert to keep my teeth apart ie. stick my tongue between my teeth or blow air in my cheeks. When I woke up today, I had a huge headache and my teeth are really sore. I'm using a heating pad to soften the muscles in my jaw right now. Does anyone know any other way to keep from doing this short of using a mouth guard, which I would really rather not do.
